有可能有這樣的需求，需要node作為web伺服器通過另外一台http/httpsProxy 伺服器發http或者https請求，廢話不多說直接上代碼大家都懂的：
var http = require(‘http‘)var opt = { host:‘這裡放Proxy 伺服器的ip或者網域名稱‘, port:‘這裡放Proxy 伺服器的連接埠號碼‘, method:‘POST‘,//這裡是發送的方法 path:‘ https://www.google.com‘, //這裡是訪問的路徑 headers:{ //這裡放期望發送出去的要求標頭 }}//以下是接受資料的代碼var body = ‘‘;var req = http.request(opt, function(res) { console.log("Got response: " + res.statusCode); res.on(‘data‘,function(d){ body += d; }).on(‘end‘, function(){ console.log(res.headers) console.log(body) });}).on(‘error‘, function(e) { console.log("Got error: " + e.message);})req.end();這樣我們就通過了指定Proxy 伺服器發出了https的請求，注意這裡我們同Proxy 伺服器是http協議的，不是https，返回的結果當然肯定會根據你的Proxy 伺服器不同有所不同。
